Tutorial: Fix Invalid Dictionary Entries in Firefox

WEBINAR:On-Demand

"Firefox also has the ability to add special words to its list
of properly spelled words in case you've got a proper name you use
often, or an alternative spelling of something, that you don't want
to get flagged all the time, or you want spell checked with the
rest of the words.

"To do that, you'd normally right click on the red highlighted
word and select "Add to Dictionary". However, sometimes in our ever
so wonderful gracefulness, we can sometimes add words to the
dictionary that are not proper spellings and that we did not want
added. So how do you remove those? Well, it's really quite
easy."
